HENRY, a citizen of' the United" States, residing at Philadelphia; inthe: county of wFhiladelphia anchState of- Pennsylvania, have inventedcertain new and l useful -2Improvements* in Clutches; and'ilf do=hereby{declarcthe following to-be'a full, clear, and exact descriptionof the invention, such-aswill enable others skilled in the art "towhichit appertains to illit-ke allfl'llse' the83.11162 1 This inventionrelatesto clutches and has for an objectto provide clutch for use inconnection" with a rapidly rotating-"- shaft with means'rfo'r picking{up anothei shaft at a speed less-than the" speed of rotation' of theshaft. 1 1

jLIt' is well known that it'is dangerous t0 the mechanism to picki'lptwith' a clutch from a rapidly rotating member. The' pr'esentinvention, therefore, embodies means for picking up the motion a speedvery much less than the speed of rotation of the shaft and immediatelyconverting such speedinto the maximum speed of the shaft.

Like characters of reference designate corresponding parts throughoutthe several views.

The improved structure which forms the subject-matter of thisapplication is adapted to operate in conjunction with a shaft 10 rapidlydriven in any approved manner as by the pulley 11.

WVithin the clutch housing 12 the shaft 10 is provided with a gear 13which, of course, rotates simultaneously therewith. The housing 12 isalso provided with an internal gear 14 with idlers 15 rotating betweenthe gear 13 and the internal gear 14, such idlers having planetaryrotation upon trunnions 16, carried by spiders 17 and 18 free to rotatewithin the housing 12 about the shaft 10. The relation of the gears isimmaterial to the present invention but as shown in the drawingespecially at Figs. 2 and 3 it will flpec ification of Letters Patent.

be-obvious that the spiders 17 and 18 will rotate about onee 'to -fiverevolutions :ofv the" shaft 10: .The spider 18: carries-a clutch face 19and a clutch member 20 isvmounted freely upon the shaft 10 and to slidelongitudinally relative to the housing 112' by means of a splinedco1n1eotion21us'A spring 22 is adapted to throw the clutch member 20 Einto engagement with the clutchriface K19 when the clutch member ispermitted to move. The clutch member 20 1 is 1 held normally out ofengagement with the clutch face 19 by means of a bolt '23 engaging camcollar 24. 1 The bolt 23is operatedmair ually or ineclianioally by anyapproved means as the lever 25 and whelrre1easedper mits the clutchmember. 20to move slidably intoengagement witlrtheclutch face19. As the'clutclrmember- 20 is=held against rotation relatie to theihousing12ritis obvious that when such clutch-member engages the clutch fa-ce 19it-"will pic'lcup the lmotionof' thespiderl-S and r'otatethe housing 12initi ally at such speedl It will thus be obvious that the housing 12 ispicked up at a speed much-less thalrli the rotation of the shaft 10,that is to say as the parts are proportioned in; the "drawing *about one=to five. About one part of the housing 12 a casing 26 is located withroller clutches 27 of substantially the usual and ordinary type sothatas the housing 12 is rotated it also picks up the casing 26 whichcarries means for transmitting the power as the gear 28. As the housingrotates the bolt 23 is let back into position to engage the collar 21when it is desired to disengage the clutch and by engagement against thecam by its own motion and power forces the clutch member 20 out ofengaging position as shown at Fig. 1.

As an example let it be supposed that the shaft 10 is rotating at fivehundred revolutions. The cam face 19 of the spider 18 is, therefore,rotating at one hundred revolutions. The clutch member 20, therefore,engages not at five hundred revolutions but at one hundred revolutions.Immediately after the engagement of the clutch member 20 with the clutchface 19 the housing 12 is rigidly locked with the shaft 10 and jumps tofive hundred revolutions. Another clutch,

however, is interposed between the housing lPatented Juned 1 918.Application filed October 11,1915. Serial No. 55,278.

jumping to the maximum speed and then introducing a second clutch toease the jerk incident upon picking up the high rate of speed it isfound that a positive clutch can be employed upon rapidly rotating partsWithout fear of breakage or stripplng of the parts.

I claim:

1. The combination of a rapidly rotating part embodying a gear, aninternal gear normally stationary, a planetary gear revolving about suchfirst mentioned gear at a slower rate of speed and intergeared with theinternal gear, a member journaling the planetary gears and carrying aclutch face and a clutch member adapted to engage the clutch face of thegear journaling member and look all into a unitary structure.

2. The combination of a rapidly rotating shaft and a gear thereon, ahousing surrounding the shaft and gear and embodying an internal gear,planetary gears revolving between the first mentioned gear and theinternal gear, spiders rotating about the shaft and journaling theplanetary gears and carrying a clutch face, a clutch member held againstrotation relative to thehousing and adapted to inter-engage with theclutch face of the spiders and means to take power from the housing.

3. The combination with a rapidly rotating shaft and a gear thereon, ofa housing surrounding the gear and embodying an in ternal gear, spidersmounted to rotate upon the shaft and relative to the housing andcarrying a clutch face, planetary gears carried by the spiders andinterposed between the gear of the shaft and the internal gear, a clutchmember held against rotation rela tive to the housing and adapted toengage the clutch face carried by the spiders and means to take powerfrom the housing.

at. The combination with a rapidly rotating shaft and a gear thereon, ofa housing surrounding the gear and provided with an internal gear inplane with the gear of the shaft, a spidersurrounding the shaft and freeto rotate relative thereto and to the housing and carrying a clutchface, planetary gears journaled upon the spider and inter-geared Withand free to rotate between the gear of the shaft and the internal gear,a clutch member slidable relative to the housing but held againstrotation relative thereto and adapted to engage the clutch face of thespider, a roller clutch member adapted to take motion from the housingand means to. take power from the roller clutch member.

In testimony whereof I afiix my signature in presence of two Witnesses.
